Abstract
Process for obtaining a steroid Δ 4-3-keto-9 α -halo-11 β -hydroxy-17 β -oxi-17 α -alkyl, characterized in that it comprises the operation of reacting with a halogenhydride, whose halogen it has an atomic weight of 19 to 36 inclusive, a steroid Δ 4-3-keto-9,11 β -epoxy-17 β -oxi-17 α -alkyl, in which the group 17 α -alkyl, contains less than 3 carbon atoms and the group 17 β -oxi is selected from the group consisting of hydroxy and acyloxy, wherein the acyl radical is that of an organic carboxylic acid containing from 1 to 12 carbon atoms inclusive, to thereby produce a steroid Δ 4-keto-9 α -halo-11 β -hydroxy-17 β -oxi-17 α -alkyl.
